"I want to be available, I don't want to waste Anushka Sharma and Katrina Kaif's dates... I want to be very clear that I don't want to waste their dates. They have signed two films. Katrina has 'Thugs of Hindostan' and Anushka has 'Sui Dhaaga'. I want to be available," the actor said.

On being prodded further about whether they have discussed the next film in 'Dhoom' franchise, he said there has been no offer from Yash Raj Films.

"With Yash Raj, there is no offer. They just tell me. But I have explained to Aditya Chopra, Karan Johar and my other director friends that I am not thinking of any other film till December, they understand and respect that," he said.

Currently, the actor is busy shooting for Aanand L Rai's film, in which he plays the role of a dwarf.
